Question

manoj travel 1/3rd of distance at an average speed of 16km/hr

Answer 1

Answer:

Let's take total distance travelled in parts are 6

We have to find here Average Speed = Total distance travelled / Total time taken

Total distance travelled in parts are 6

Total time taken = distance_1/speed_1 + ....

1st one is 1/3rd of distance which is 1/3rd of 6 = 2 at speed of 16km/h

2nd one is 1/2 of distance which is 1/2 of 6 = 3 at speed of 15km/h

Average Speed = 6/ (2/16 + 3/15 + 1/20)

= (6/15)*40

We have Average Speed now & total time also A.T.Q = 15 hours

So Total distance = Average Speed * Total time

= (6/15)*40 * 15

= 6*40*15/15

= 6*40

= 240 Km

Ans = 240 Km

I hope it May helpful to you ...
